With the ever intensifying CO2 neutrality and ambitious climate agreements, alternative clean energies,

in particular, hydrogen is gaining its momentum. The reason being carbon free energy conversion and

high gravimetric energy density of hydrogen. In order to integrate compressed hydrogen into vehicles,

lightweight, safe and inexpensive pressure vessels are necessary, which at the same time should be

capable of serial production. [1]

Current state of the art carbon fibre reinforced plastic (CFRP) pressure vessels, consisting of carbon

fibres, liner and metallic bosses, are produced by filament winding. These designs need huge amounts

of CFRP-material around the dome area to transfer the axial forces into the lamina.

Primary objective of the project is to exploit the advantages of composite materials and thereby

accounting to material reduction. To achieve this, the patented load introduction of the IVW is used to

integrate the metallic dome in the CFRP-Material. With this load introduction developed for highly

loaded tension rods, the axial loads of the dome can be introduced individually into the axial layers via

single layer placement without having to wrap the entire dome. This distributed load introduction into

the individual fibre layers avoids stress peaks and thereby ensures a high suitability for lightweight

design. Because of its design, the lamina consist only of 0°-axial and 90°-circumferential layers and the

fibres lie along the load path. This provides a high cost-saving potential for CFRP.

In addition, there is a wide range of pressure vessel diameters possible. This enables a high packing

density and thus efficient use of design space. This gives a high degree of design freedom in the tank

design.

The aim of this study is to use the concept of the IVW-load introduction for hydrogen pressure tanks

and to verify the potential of this design.
